I would like to back up my huge email history which is saved in numerous sub-folder folders on my Windows 11 computer. According to Thunderbird settings, my profile should be at the default location: C:\Users\jorda\AppData\Roaming\Thunderbird\Profiles\5ypfc1q9.default-release\ImapMail\imap.dreamhost.com But when I open the AppData folder, there is no sub-folder named "Thunderbird". In the "View" menu, "show hidden items" is checked. In the Troubleshooting menu, under Application Basics, Profile Folder, when I click on "Open Folder (Local drive)", I get a message saying: "C\Users\jorda\AppData\Roaming\Thunderbird\Profiles\5ypfc1q9.default-release is unavailable. If the locatoin is on this PC, make sure the device or drive is connected or the disc is inserted, and then try again. If the location is on a network, make sure you're connected to the network or Internet, and then try again. If the location still can't be found, it might have been moved or deleted". Yet Thunderbird is still working fine and all my past emails are accessible. I'm stumped - can anyone help me find or expose my Thunderbird profile folder?
